Lawyers for California customers of The DirecTV Group Inc. have filed a preliminary injunction motion seeking to stop the satellite television service from automatically withdrawing early cancellation fees from customer bank accounts and credit cards without their knowledge or consent.

The motion, filed on Sept. 21 in Los Angeles Superior Court, came in a lawsuit alleging that DirecTV fails to adequately disclose the fees, which range up to $480, when customers sign up or change their service. The suit claims that DirecTV does not inform customers that their terms of service usually run between 18 and 24 months.
